Monitor dead - Philips Computer Monitors


Answers :

If the monitor has no power at all then you have a dead power board, or a broken power cord, test also a different wall AC outlet.

If instead there is a flashing led on front of the monitor, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1\015\012The internal circuits are jammed because of electrostatic charges\015\012accumulating on capacitors, or because of a wrong voltage read by the\015\012main chip on your monitor controller board. this started the protection\015\012circuit.

2 The protection circuit detected a wrong voltage or a\015\012broken contact, identified an internal fault and kicked in , starting\015\012the flashing light.


If you are in situation one, then the\015\012monitor will reset just unplugging power cord for one or two hours,\015\012sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common\015\012faults that can occurr suddenly are a blown capacitor on power board,\015\012the inverter board powering up backlight lamp has blown, or a fault on\015\012main lcd controller board.
check also the video cable, if the cable\015\012is shorting, or the connector is bad, you can get same flashing state\015\012because of the video cable.

Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.
